Abstract

Frog’s group of Hylarana nicobariensis (Stoliczka, 1870) is a complex species that has diverse genetic populations and variations on advertisement calls. Variations on advertisement calls among populations have been reported in Sumatra, Java and Bali. The population of frog in Enggano has different phenomenon that was not found in Sumatra and Java.  Enggano population was genetically identical, but the advertisement calls were very diverse. There were four types of advertisement calls on the population in Enggano Island, namely: (1) advertisement call type 1 which has pulse wave with the dominant frequency of 2855.13 ± 135.22 Hertz; (2) advertisement call type 2 which has pure tone wave with the dominant frequency of 2720.29 ± 97.69 Hertz; (3) advertisement call type 3 which has pulse wave with dominant frequency 2634.61 ± 292.81 Hertz; (4) advertisement call type 4 which has pure tone wave with dominant frequency 1618.79 ± 83.05 Hertz. The degradation of the dominant frequency and the lower frequency was likely due to the increase of snout to vent length (SVL) of adult male that were followed by increasing the size of the head.

Abstract

Previous ecological studies have revealed the types of non-forest frog commonly occupying habitats that have been modified by humans are still severely limited. For that purpose the research was conducted in the wetland area of Ecology Park in LIPI Campus Cibinong which is located at S 06" 29 40.2"; E 106° 51 06.3" with 165 meters altitude above sea level (asl) over seven months (May-November 2009) by monitoring 14 times during the study period (July-November).The transect method was used to determine the effect of habitat on the diversity and abundance of frog species in the wetland area. Transect was set for 100 meters on one side of the lake where the area has a variety of habitat types. Length of 100 meters transect was divided into 10 sections with 10 meters length for each section, (length of each section was 10 meters). Every 10 meters, the type of habitat, frog species encountered and the abundance of the species were recorded. Environmental data recorded were air humidity, air temperature, water temperature and moon phase (full moon, crescent moon or the dark moon). Ten frog species which belong to 4 families, the Bufonidae (Bufo biporcatus and B. melanostictus), Microhylidae (Kaloula baleata), Ranidae (Fejervarya cancrivora, F. limnocharis, Rana chalconota, R. erythraea, R. nicobariensis and Occidozyga lima) and Rhacophoridae (Polypedates leucomystax) were found.R. erythraea, R. nicobariensis and O. lima were the dominant species and found on every visit. Furthermore, the most dominant species was R. erythraea. The results showed that environmental factors (air temperature, water temperature, humidity and conditions of the moon) did not have an impact on the presence and number of species. Abundance of three dominant species (R.erythraea, R. nicobariensis and O. lima) was strongly linked to vegetation type. Moreover, environmental factors (water temperature, humidity and the condition of moon) affected the abundance of R. nicobariensis in sub transect 2 and 5 where dominated by Eleocharis dutcis ans Leerxia hexandra. On the other hand air temperature affected the abundance of O.lima in sub transect 7, dominated by floating lotus plant Nymphaea lotus.

Abstract

Habitat loss and fragmentation are among the largest threats to herpetofauna diversity in tropical rain forest areas, including the rain forest in Kerinci Seblat National Park (KSNP). To measure the rate of negative impact to the herpetofauna population,fifteen survey sites with several degree of habitat disturbance were selected. Based on cluster analysis,15 survey sites were grouped into five distinct clusters, included low elevation forest group, high elevation group, swamp group, disturbed forest group and cultivated land group. Calculation of linier regression for four major (low elevation forest group, high elevation group, disturbed forest group and cultivated land group groups) showed that the rate of locally biodiversity losses were high (R2 > 0.7).

Abstract

Selama survai herpetofauna di Taman Nasional Ujung Kulon yang dilakukan pada bulan Juli sampai September 1990 dijumpai 14 jenis amfibia; yang terdiri dari satu jenis dari suku Megophryidae, tiga jenis dari suku Bufonidae, tiga jenis dari suku Microhylidae, lima jenis dari suku Ranidae dan dua jenis dari suku Rhacophoridae (Kumiati el al.. 2001). Survai herpetofauna Iain terutama untuk kelompok amfibia pernah dilakukan Liem (1973) di Taman Nasional Gede-Pangrango. Survai tersebut berlangsung pada tahun 1961-1962, dan lebih intensif lagi dilakukan pada bulan Agustus 1963, Maret dan Mei 1964. Dari survai ini Liem (1973) mendapatkan 19 jenis amfibia; yang terdiri dari dua jenis dari suku Megophryidae, empat jenis dari suku Bufonidae, dua jenis dari suku Microhylidae, tujuh jenis dari suku Ranidae dan empat jenis dari suku Rhacophoridae. Untuk mendapatkan gambaran umum keanakaragaman herpetofauna dari tiga taman nasional yang terdapat di Jawa Barat, maka dilakukan survai herpetofauna di Taman Nasional Gunung Halimun; yang berlangsung intensif sejak bulan Oktober 2001. Dua puluh dua jenis amfibia didapatkan selama survai tersebut; yang terdiri dari dua jenis dari suku Megophryidae, empat jenis dari suku Bufonidae, satu jenis dari suku Microhylidae, sepuluh jenis dari suku Ranidae dan lima jenis dari suku Rhacophoridae. Indeks kesamaan Simpson digunakan untuk membandingkan keanekaragaman jenis antara dua taman nasional. Hasil indeks koefisien Simpson antara Taman Nasional Ujung Kulon dan Taman Nasional Gunung Halimun adalah 0,786; antara Taman Nasional Ujung Kulon dan Taman Nasional Gede-Pangrango adalah 0,786; dan antara Taman Nasional Gunung Halimun dan Taman Nasional Gede- Pangrango adalah 0,842. Berdasarkan kepada nilai indeks tersebut, kesamaan keanekaragaman amfibia di Taman Nasional Gunung Halimun dan Taman Nasional Gede-Pangrango sangat tinggi.

Abstract

Giant River Toad {Phrynoidis aspera (Gravenhorst, 1829)} is a largest generalist toad that is able to adapt to a variety of habitats and elevations. The complete calls of Giant River Toad had not been published before. To know all of sound characters of the toad, a total of five individuals males P. aspera vocalization were recorded on 30 October 2010 (1 individual; air temperature: 23.1°C; water temperature: 18.1°C) by using an Audio Technica AT875R microphone, the sound was recorded on a Fostex FR 2LE in WAV format; and on 22-24 September 2011 (4 individuals; air temperature 21.0°C-23.4°C; water temperature 21.6°C-22.0°C) in Curug Nangka, Mount Salak foot hill,West Java by using PCM-M10 Sony Recorder. The toad has four types of call: (1) Call type 1, consists of impulses without harmonic and average band width is 317.44 Hertz and average of amplitude is 40.43; (2) Call type 2, consists of pure tone with many sub-harmonics, average range frequency is 1420.28 Hertz and average of amplitude is 42.67; (3) Call type 3, consists of impulses and pure tone with two weak harmonics and average band width is 373.81 Hertz and average of amplitude is 48.19; (4) Call type 4, consists of impulses without harmonic and average band width is 792.62 Hertz and average of amplitude is 51.01. Based on the number of calls that were recorded of five individuals from the Mount Salak foot hill, call type 4 is its major call (common advertisement call), but the three others call types are minor calls.
